We bought a couple of items at various times from Craigs list arranged for midday meeting in the parking lot of a busy fast food restaurant. Not gonna say who was carrying. But I tend not to take chances.
The local police department has a designated, well lit, area of their parking lot designated for transactions. Security cameras plus cops coming and going.
YUP!
I bought some antiques once from a very nice and most attractive lady in Austin, Texas. I meet her at her home and she was alone. I suspect she was an Austin Liberal.
After buying them and loading them into my truck I turned to her and said, "You are a very nice and attractive lady. You had no idea whom was coming into your home and you were alone. Do not do this in the future! Always have someone with you that knows how to handle and use a firearm."
